7.2.1.2 Relationships with other components

The EHM terminal can access the EHM application server and IoT platform via the communication
network. It can access the EHM application server directly or via the help of the IoT platform.

7.2.2 EHM end point
The EHM end point is defined as an EHM device connected with the communication network via
gateway(s) [ITU-T Y.2065]. The characteristics of an EHM end point are given according to the
following aspects:

7.2.2.1 Functions
The functions of the EHM end point include:

(F-EEP-1) EHM data sensing and collection:
The EHM end point can sense and collect EHM data from EHM customers or related environment.

(F-EEP-2) EHM application running
The EHM end point can support running of EHM applications according to the EHM end point's
usage purpose.
(F-EEP-3) Connection to EHM gateway

The EHM end point can connect to the EHM gateway via local wireless or wired communication
technologies.
7.2.2.2 Relationships with other components

The EHM end point can directly connect to and access the communication network via the EHM
gateway. The EHM end point can also access the IoT platform and EHM application server via the
EHM gateway and the communication network.

7.2.3 EHM gateway
The characteristics of an EHM gateway are given according to the following aspects:

7.2.3.1 Functions
The functions of the EHM gateway include:

(F-EG-1) Gateway application running

Gateway applications can run on the EHM gateway.
(F-EG-2) Connection to the communication network
The EHM gateway can connect to and can communicate with other components via the
communication network.

(F-EG-3) Connection to EHM end points
The EHM gateway can connect to EHM end points via local wireless or wired communication
technologies.
(F-EG-4) EHM end point connection support

The EHM gateway can provide support for the connection of EHM end points to the communication
network.
(F-EG-5) EHM service support
The EHM gateway can support the interworking of EHM end points with the IoT platform and EHM
application server. Also, it can handle operations and data exchanges with the IoT platform and EHM
application server.
